7 Aloe Vera Health Benefits Backed by Science

Which Aloe Vera Health Benefits Should We Believe? 

So many health benefits are claimed for Aloe Vera that it is difficult to know which ones to believe and which are quackery or made up by manufacturers to sell more products. So we decided to go back to the books and try to work out what is backed up by science, and what is yet to be proved.

Here is what we found out: 

Aloe Vera with a Pestle and Mortar to Illustrate its many Health Benefits

Aloe Vera Gel is thought to contain over 200 different chemicals of which about 75 have been identified, but it is not known exactly which of the compounds are responsible for the healing effects.  It is most likely to be the combination of many of the substances contained in the gel which makes it effective.

Since this makes it difficult for any drug company to isolate or replicate the exact formula for the active compounds, pharmaceutical companies tend not to invest large sums in researching Aloe Vera.  For this reason, there is still much work to be done before we understand the real therapeutic benefits of the 'miracle plant'. 

So, although there are undeniably health giving substances in Aloe Vera, there is a lot more work to be done to find out how it works, and to extract or copy the healing ingredients so that reliable medicines can be produced with reproducible effects. So far, there has been quite a large variation in the results of various studies, because of different extraction methods, dosages, and shelf life of the ingredients. Fresh Aloe Gel is often the most effective, but that doesn't help the drug companies! 

It is widely agreed among scientists that Aloe Vera is safe to use on the skin, but more research is needed before it can be stated that it is 100% safe to take internally.

Research into Aloe Vera Medicinal Uses are showing it is:

  1. Anti-viral
  2. Anti-inflammatory
  3. Anti-bacterial
  4. Anti-fungal
  5. Anti-oxidant - acting against free radicals in the body from pollutants, cigarette smoke and other things which are bad for us.
  6. Anti-allergic
  7. Analgesic (pain killing)

It has also been shown to be effective against cancer in animal trials. 
However, few mainstream pharmaceuticals have been produced using this plant and Aloe is not listed on the FDA’s "Generally Recognized as Safe" list due to a lack of studies about its safety.

There has been one study showing that whole leaf extract was carcinogenic in rats, although it did not have the same effect in mice. More research is needed to ascertain the risks for humans.  Therefore, it is advisable to be cautious when taking Aloe Vera internally.
